The 30-share index dropped 140.51 points, or 0.40 per cent, to 36,129.56 points in opening trade. The gauge had rallied over 1,310 points in the previous five sessions.

The NSE Nifty too fell 47.50 points, or 0.44 per cent, to 10,840.85. Among sectoral indices, IT fell the most 1.19 per cent, followed by tech 1.08 per cent, on account of appreciating domestic currency.

Meanwhile, FMCG, healthcare, banking and consumer durables also fell by up to 0.35 per cent as profit-taking emerged on these counters.

Brokers said, the decline in benchmark indices was on account of a weak trend in Asian markets amid sharp losses at the Wall Street, as investors continued to fear to weaken global growth.

Besides, profit-booking in recent gainers also dampened investor sentiment here. Infosys emerged as the worst performer in the Sensex pack, falling 1.67 per cent, followed by Wipro at 1.49 per cent on weakening the dollar against the rupee.
